Abstract: PURPOSE:To reduce the switching loss of a semiconductor switching element such as FET by providing a time-constant circuit between the drive winding of a transformer and the semiconductor switching element and by turning ON the semiconductor switching element at the time when the value of drain voltage of the semiconductor switching element becomes zero. CONSTITUTION:When FET1 is turned ON, electric current flowing through the FET1 rises rectilinearly so that magnetic energy is stored in the exciting inductance of the primary winding N1 of a transformer T and the FET is turned OFF. When the FET1 is turned OFF, the exciting inductance of the primary side winding N1 and a capacitor C1 resonate and respective voltages of the primary side winding N1, secondary side winding N2 and drive winding N3 rise so that output current is supplied to a load 70. When the energy of the exciting inductance of the primary side winding N1 moves to the load side, the voltage of the primary side winding N1 changes in the zero direction and a time-constant circuit 60 turns ON the FET1 at the time when the drain current of the FET1 becomes zero.

Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable multilayer ceramic capacitor, free of structural defects and having a low short-circuiting rate by controlling the particle size distribution and specific surface area of a powdered material of which a ceramic green sheet is made.
